Title: Automatic screw adjuster for vehicle brakes
Inventor: EDWARDS ROY ERNEST
IPC: F16D65/56
Filed: 1962-12-14
Abstract: 1,037,482. Disc brakes. GIRLING Ltd. Dec. 10, 1963 [Dec. 14, 1962], No. 47368/62. Heading F2E. A lever-operated disc brake comprising a disc 14 and two brake-pads 10 and 11 applied by an actuating lever 16 has an automatic adjuster responding to movement of the lever 16 in the brake applying direction which adjusts the position of the pads when their clearance from the disc exceeds predetermined value and is provided with resilient means 34 which yield on further movement of the lever 16 after the brake pads have been applied. The pads 10 and 11 are carried respectively on a reaction lever 12 and a servo-lever 13 which are mounted on a fixed pivot 50. The actuating lever is pivoted near one end at 17 on the servo-lever 13 and carries an hydraulic cylinder 19. The piston-rod of the hydraulic cylinder (seen in cross-section in Fig. 1), when under pressure, bears against a boss 20a at the fixed end of the lever 13 to cause the lever 16 to operate the pads through a strut 18 against a return spring 41. A spring 42 connects the lever 16 to the boss 20a and causes it to return when the cylinder 19 empties. The reaction lever and servo-lever are interconnected by a pull-rod 21 having a part-spherical head 22 seated in the lever 12 at 23 and a part-spherical nut 25 on its screw-threaded end 24 which engages with a sealing 26 in the lever 13 located in alignment with the pivots 17 of the lever 16. The nut 25 has ratchet teeth 27 in a plane normal to its axis engaged by mating teeth on a flat-face pawl 28 carried on a shoulder 29 of the nut and urged into engagement by fingers 30 on a spring- steel ring 31. A flexible cable 33 connects an extension 32 on the pawl 28 to a coiled spring 34 held in compression in a retaining-box 35. The closed end of the retaining box is connected by another flexible cable 33 over a pulley at 37a to the fixed boss 20a; movement of the lever 16 on actuating the brake thereby causes a movement of the face pawl (clockwise in Fig. 1) against a spring 45. If, due to wear of the pads, the movement of the pawl before the pads engage is greater than the pitch of one ratchet tooth the pawl will be engaged by the spring 45 in a fresh position on the ratchet and the nut 25 will be rotated to adjust the clearance of the pads. Due to the high force of the hydraulic cylinder, resilient deflection of the lever 16 may take place after the pads are engaged, but since the nut 25 is locked on its thread by the pressure it does not move and any consequent tension on the cables 37 is taken up by the spring 34.

Title: Improvements in or relating to colour television receivers
IPC: H04N9/465
Filed: 1964-11-26
Abstract: 1,083,463. Colour television. BLAUPUNKTWERKE G.m.b.H. Nov. 26, 1964 [Nov. 29, 1963], No. 48033/64. Heading H4F. In an arrangement for demodulating a PAL colour sub-carrier signal in order to derive R-Y and B-Y signals the demodulation axes for the two synchronous demodulators are mirrored about the Q axis at line rate in synchronism with alternation of the I-axis modulation between I and -I. Thus, as illustrated in Fig. 5, assuming the reference oscillation to have the R-Y phase angle, in one line it is applied directly to the R-Y demodulator and with a 90 degrees phase lag to the B-Y demodulator, whilst in the next line it is applied with a 24 + 90 degrees = 144 degrees phase lag to the R-Y demodulator and with a 24 degrees phase lag to the B-Y demodulator. A suitable circuit is illustrated in Fig. 6 where 43 and 47 denote the B-Y and R-Y demodulators. The reference signal appearing across a resistor 75 is applied through series resonant circuits 73 and 74 to the demodulators and also to opposite ends of a 90 degrees phase shift circuit 66, the connections being made through diode switches 62 and 63 which are rendered conductive alternately at line rate by a bistable circuit 50 triggered by line synchronizing pulses 53. Resonant circuit 73 is detuned to introduce a phase shift of 24 degrees. In an alternative arrangement the resonant circuit may both be detuned so as to produce opposite phase shifts of 12 degrees and the reference signal across resistor 75 may be preset 12 degrees off the R-Y axis. In a modification the demodulators may be supplied with a reference signal of fixed phase and the colour sub-carrier may be applied via the phase-shifting circuits.

Inventor: HAWKINS EDWIN GEORGE EDWARD
IPC: C01B15/026
Filed: 1965-11-20
Abstract: H2O2 is obtained by oxidation of a cycloalkanol (e.g. cyclohexanol) to give a cycloalkanone and peroxides. H2O2 is extracted from the reaction mixture with an aqueous soln. of an acid or base.  An initiator (e.g. 1-hydroxy - 11 - hydroperoxy - dicyclohexyl peroxide) may be added and autoxidation may be initiated at 120-125 DEG  C. and continue at 100-110 DEG  C. so as to obtain a conversion of not more than 7 mole per cent.  The reaction mixture may be mixed with an inert organic solvent (e.g. benzene, petrol, CCl4 or CH2Cl2 before extraction with the aqueous acid or base.  If the extracted H2O2 soln. is too dilute it may be contacted with further quantities of reaction mixture until the H2O2 solution has reached a useful concentration.  Acids useful in extracting H2O2 are H2SO4, H3PO4 and HCl; bases include the alkali metal hydroxides; they are preferably used as dilute solns., e.g. containing 0.1 to 10% by weight of acid or base.ALSO:Cycloalkanones and cycloalkanone peroxides are obtained by the autoxidation of cycloalkanols. On completion of autoxidation which may be initiated by a peroxide compound and which may take place at temperatures up to 130 DEG  C., H2O2 which is formed is removed by extraction with an aqueous soln. of an acid or base.  The cycloalkanone formed is then distilled off and may be reacted with the H2O2 extracted to give a precipitate of cycloalkanone peroxide.
